Performance Test Record
Table 4-1 is a form you can copy and use to record the performance
verification test results of the HP E1418A. This table shows the output
accuracy, measurement uncertainty, and the test accuracy ratio (TAR)
values. The test marked with a “ Q” in the table are the Quick Verification
Tests.
Test Limits
The test limits are defined using the 90-day specifications. Appendix A lists
the HP E1418A specifications.
Measurement
Uncertainty
Measurement uncertainty has been calculated using the HP 34401A 90-day
specifications. The HP 34401A is set to the 6
1
⁄
2
digit mode for all
calculations. In both the voltage and current measurement mode, the
measurement uncertainty is given as:
M.U. = % of r % of range
Voltage Output
Measurements
The 100 V range is used for the voltage output measurements.
The specification is given as:
M.U. =
±
(0.0035% of r 0.0006% of range)
